Final answer:
The mass of aluminum atoms can be determined by multiplying the average atomic mass of aluminum (26.98 amu) by Avogadro's number.
Step-by-step explanation:
The mass of aluminum atoms can be determined by multiplying the average atomic mass of aluminum (26.98 amu) by Avogadro's number. Avogadro's number is a fundamental constant that represents the number of atoms or molecules in one mole of a substance, which is approximately 6.022 × 10^23 particles. By multiplying the average atomic mass of aluminum by Avogadro's number, we can calculate the mass of one mole of aluminum atoms.
So, the mass of aluminum atoms is approximately 26.98 g/mol.
For example, if we have 3 moles of aluminum atoms, the mass of the aluminum atoms would be calculated as:
3 mol Al x 26.98 g/mol = 80.94 g Al
